<P>
An image Field is a Field with regular positions and with regular
quadrilateral connections.
Images also contain a "colors" component.
The sign of the deltas of the "positions" component determines the
orientation of the image.
<P>
Functions of the routines listed here include creating a field image,
returning a pointer to the data in an image field, and
returning information about an image.
